lb allwhom it may concern; I

Be, it known that I, HQRATIO T1 FRosr, a citiaen' of the. United States, residing at Vivian in tl'ie'county of Lyman and State of Son 11 Dakota, have invented certain new and usefulImprovementsin Molds for vVentilatedConcrete \Valls,of which the followferenhthicknes'ses-and provided with means wherebyIt-hemold may be raisedafter each molding operation.

Another object of the'inVent-ion is to provide 'am'old for double-wall concrete buildingsyin *whiclia core for forminglthe ventilating or dead ,air space between the two members of the wall shall be of slightly tapering form, so that the mold can be raised readily after each molding operation.

1 Still another object of the invention is to provide a mold for concrete walls in which the sides of the mold are movable away from the'wall in order to permit the mold to be.

raised without interferingwith the surface of the wall.

Another object ofthe invention is to provide adjustable cut-off devices arranged to be movable in the mold for forming door and window openings inthe walls.

These and otherobjects may be attained by means of the construction illustrated in the accompanying drawings in which,

Figure 1 is a plan View of two members of the mold forming the corner of the wall, said two members being connected together and the supporting posts being shown in section;

Fig. 2 1s a side elevation of one of the sections of the mold. Fig. 3 is a vertical section onthe line 33 of Fig. 1, looking in the direction, indicated by the arrow. Fig. 4 is a detail perspective View showing the man- .ner in which the mold sections are connected at the corners. Fig. 5 is a'plan View of one -of the molds, showing the adjustable cut-off devices for frjrming openings for doors and windows. Fig. 6 1s a sideelevation of the "same with one member of the mold broken away to better illustrate the interior construction. F ig. 7 is a vertical sectional View on the line -70f Fig.6, looking in the direction indicated by the arrow. Fig. 8 is a detail perspective View showing a portion of the double wall with means for anchoring the two walls together. Fig. 9 is a. side elevvation showii'ig-tw-o of the supporting posts with means for raising the mold sections.

Referring to the drawings the numerals 1 designate the members of the mold sections, said members-being preferably formed of wood and provided with metal linings 2, the front one of which may be provided with a roughened surface 3, as shown in figure 3 toform a" roughened or rock-like surface to the outer surface of the building. The mold members 1 are provided with standards or uprights &' secured to the outer sides thereof and projecting above the upper edge of the mold sections 1. At the corners'the outer mold v sections are connected together by means of pivoted latches 5 or other suitable The core 6 for forming the intermediate ventilating or dead air space comprises a hollow, preferably sheet metal device closed at the sides and bottom and open at the top, said core being .of tapering form, as shown more particularly in Figs. '3 and 7, and of less width'at the bottom than at the top. Connected to the inner walls of the core 6 are curved supports 7, said supports being pivoted at their upper ends in the standards" 4: for a purpose which will presentlyappear. I

The standards are connected by adjustable braces 8 provlded' with ad ustingperform -tions 9 and adapted to be connected by means of a rod l0,which extends through the perforations 1n the two members of the adjustable braces for permitting the mold sections? 1 to be moved toward and away from the core to provide a thickeror. thlnner wall. Connected near the upper ends of the standards lare adjustable braces 11,.said braces being also adjustable by means of"v perforations and a connecting rod in the same manner as the adjustable braces8..- It i will thus be seen that the side members 1 of the mold may be adjustable toward and. a

from the core 6 by means-of the braces 8 and 11 and that the core supports Tbeing pivoted in the standards t will permit of this adjustment. In molding walls of this character, especially when one of the walls s provided with a roughened surface, it i necessary to move the members outward slightly before the mold'is raised for another tier. B'y removing the rod 12 the members may be swung apart upon the rod 10 as a pivot when necessary to move the members outward beforemolding another tier. The construction thus fardescribed' will permit of this movement of the side members of the mold. The rods 10 and 12 may be connected together by means ofsuitable couplings 13, when two or more sections are connected-together for forming a continuous wall, and

,at the corners right angular couplings 14 are provided.

For forming openings 1n the walls for window and door frames, I;have provided adjustable cut-ofi 7 devices 6 and the inner walls ofthe' members 1, said platesbeing disposed in pairs connected at their upper ends by means of a cross rod 17. Each of the plates 16 is provided. with an angular flange 18 and'pivotally, connected at 19 to said flanges are the adjustable-arms 11 and 9, sald 7. flhe arms 20 20, said arms being brought. together in the center at their upper ends and pivoted at 21 to a supporting eye 22 mounted upon the rod 12. Guide eyes 23 mounted to slide on the connecting rod 10, are provided'with bentportions 24; extending over the cross rOds'lT, as, shown more particularly in-Fig. are provided with slots 25 at their lower ends to permit the adjustable movement of the cut .ofi's 16. It will thus be seen that the cut-oil's can be moved to adjust the .width of the opening for the door or I window frame.

For raising and lowering the mold sec-.

tionsafter-each tier of the .wall is-formed, I

provide upright posts 26, as shown in. Figs.

pins 30, which extend Ropes or ca... bles 31 are connected at their lower ends to the rods 10 and 12, as shown in F 9, said ropes or cables passing over-pulleys 32 near the upper ends of the posts 26.-

As shown inl ig. 8, the two members 33 of the wall are provided with cross anchors or ties 34; made preferably in rectangi'ilar form of round or square rods or bars. These anchors or ties are laid upon the tops of the tiers after they are molded and when the" nexttier is molded these ties are enrbedded within the tops offthe tiers. Other "suitable ties or anchors may be provided.

I have alsoshown longitudinal reinforcing rods'or bars 35 and vertical reinforcements 36 which maybe employed if desired.

The operation of my invention 'inay be come set the Y 16 comprising 7 metal plates designed to fit between the core.-

connected to said braces, pivotally suspended by curved rods. from" the standards, cutofl'devices. between the' posts being provided with:

through said posts and into the mold sections for supporting them at. any required height.

briefly described as tyllows: \V hen the db sired number of sections of the molds have been connected togv her to form the wall,

the concreteis pou ed in between. the core 55 and the mold members and after it has be mold members 1 aremoved' outwardly a slight distance and are then raised by means of theropes or cables 31' for the next tier, as will be understood.

From the foregoing it will be" obvious. that a mold made in a'ccordance'Wit-h [my invention, is simple in construction, can be quickly operated, is adjustable to' different thicknesses of walls, will provide" a. ventilating opening between the two members'of the wall and is providedwlth simple and efficient means for forming window and door openings, of varying widths.

Havingthus fully described the mven'-' tion what is claimed as new is: I I l. A mold for concrete buildings coinprising parallel members, a tapering intermeans for ad usting said mediate core, members toward and from the core, cutoi'fs for forming the door and window open-- 'ings, sald cut-ofis compr sing plates dis-- posed between the outer walls ofthe core and the inner walls of the mold members,

slotted arms 'pivotally-comlected to the cutoffs, said arms being pivotally connected t'o gether, and. means for raising and lowering the mold inembers,-the core'and the cut-offs.

2., Ainold for concrete walls comprising parallel mold members, standards connected to said mold members, adjustable braces connected tosaid standards, removablerods' a tapering core core and mold members, means for adjusting'said cut off devices,and'mealrs ifor raisnnected raising the mold members and tiprisihg pivoted to said stamlards, ftl nd' I In testimony whereof I ailix my signature.-

in presence of two" witnesses.
